The aim of this study was to compare infants' sleep measures through an actigraph and maternal parenting stress among preterm and full-term mothers, and to explore the factors affecting maternal parenting stress in relation to infants' sleep.
The subjects were 44 pairs of mothers and children. Twenty-one were in the preterm group, and 23 were in the full-term group. Inclusion criteria for preterm infants were born at less than 36 weeks and birthweight of less than 2500 g. The Parenting Stress Index (PSI) Short Form assesses maternal perception of the degree of parenting stress: the children's domain, and the parent's domain. An actigraph was applied to assess the infants' sleep measures.
The PSI showed significant differences, with high scores in parenting stress in the preterm group. Also, the number of mothers who complained about their infant's sleep issues was significantly higher in the preterm group. Most of the sleep measures showed improvement by their age in both preterm and full-term infants. Multiple linear regression analysis showed that sleep efficiency, longest sleep duration at nighttime accounted for 71% of stress in the children's domain of the PSI of the preterm group.
The parenting stress among mothers of preterm infants was significantly higher than that of mothers of full-term infants. The mothers of preterm infants were concerned about their infant's nocturnal sleep quality.
本研究旨在比较通过活动记录仪测量的早产和足月母亲的婴儿睡眠指标，以及母亲的育儿压力，并探讨与婴儿睡眠相关的影响母亲育儿压力的因素。
研究对象为44对母婴。其中21对属于早产组，23对属于足月组。早产儿的纳入标准为孕周小于36周且出生体重小于2500克。育儿压力指数（PSI）简表评估母亲对育儿压力程度的感知：儿童领域和父母领域。使用活动记录仪评估婴儿的睡眠指标。
PSI显示出显著差异，早产组的育儿压力得分较高。此外，抱怨婴儿睡眠问题的母亲数量在早产组中显著更高。大多数睡眠指标在早产和足月婴儿中均随年龄增长而改善。多元线性回归分析显示，睡眠效率、夜间最长睡眠时间占早产组PSI儿童领域压力的71%。
早产婴儿母亲的育儿压力显著高于足月婴儿母亲。早产婴儿的母亲担心其婴儿的夜间睡眠质量。
